The Direct LI-201 sensor has been temporarily moved (swapped with the LI-190) to to the outer "piggy back" lower position on the tracker, so that the Direct Quantum LI-190 sensor would not be shaded by the ventilator on the tracker to the south of the instrument. Until it gets moved to the final upper position, the sensor will be shaded between approx 9:10 and 9:40 MST of every day.

There was a planned power outage for SRRL construction activities that started at 5:18 MST. Unfortunately, the backup generator provided to SRRL was providing bad power to the UPS powering the Sci-Tec trackers, therefore the UPS failed at 5:55 MST. Unfortunately, when normal AC power was restored at 11:45 MST, the Sci-Tec trackers had lost all their configuration due to UPS cycling on and off during the outage, therefore were not tracking. The tracker settings were restored on May 9 at 7:58 MST. The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, NIP #1, LI-201, NIP RG780, CUVA2, CUVB2, TWC; and the following instruments were un-shaded: Diffuse 8-48, PSP, CM22, CUV4, PIR, CG4

The LI-201 has been having a moisture leak that has been gradually getting worse over time. Instrument was removed from service on 9/3/2008 @ 13:50 MST so that it could be disassembled and dried. Listed start date is approximate. Instrument was returned to service 9/23/2008 @ 14:00 MST, however instrument needs to be re-calibrated, since the annual calibrations on the unit were resulting in calibration factors that were artificially high (to compensate for moisture leak).
